The top surface of this third rail is curvedslightly, downwar at the ends; best shown in Fig. 3', so that the roller 2, which is csrried'by brackets 2 on the moving vehicle, will readily ride upon said rail. The spring 3 tends to press the miter end 2 of the bracket 2 in a downward, direction the object of which is to reserve a contact between the roller 2 an rail 1'.

3st and 3 1' are cog wheels ri idly attached, respectively, to shafts 35 and I 35 a hand wheel rigidly tached to the shaft y To c tin the operation of imyinvention, pal-tic 'referencelto'hig 1' is necessary. As the train passes a section 'of third rail 1, the roller 2 comes in rolling-0r slidingcom tact with it, and passes over same. When the signals indicate all clear, this contact has no operative influence on the electromechanical device carried on the train, if however, by an automatic block signaling system, or any other electric or mechanical means, danger is indicated, the train is automaticaily sto pod. This is efiected byithe interruption oi the electric current: 'ivhich the conin the energized position shown on the drawmg; said interruption of the electric current denergizes the magnets of the relay 6 and releases the armatures 6, thus allow to spring awa from the magnets an make contact with t e points 4; this contact com- ,pletes anlelect-rical connection between the third rail 1 and a rail section 1 of the main them,

track through the conductors 4 and 5 and-armature 6 of the rela 6, said main track rail section being insu ated from the rest of the track by the insulators 1".

The closing of this circuit by the contact wheel 2 touching rail 1,.starts a current from the battery 9 through the circuit and energizes the relay coils 14 and magnet 14' so that the armature 14' is drawn toward the magnets and contacts with 14 and is held in this osition b mechani cal means until released.

A variety .of causes put my invention into operation,' a short description of some of which will plainly show its great value and utility. 1st: 11 a railway block signaling system equipped with my device, if a train fitted with my portable apparatus, attempts to overrun a danger signal and gets into a block which already has a train in. it, or for any reason is signaled as dangerous, the

train so fitted is stopped automatically in the manner hereinoefore explained. 2nd: A train despatcher may have a key so Wired to a signaling system circuit that he can at willbreak said circuit and automatically stop a train eta particular. point. 3rd: on a rail Way line the vehicles of which are equipped with my apparatus and Wired especiall for same, as for instance Where no" other lock or interlocking signaling system is in use, the battery and circuits can be arranged as shown on Fig. a. By this arrangement, any train is proteotedtrom collision either from ahead or behind, for any desired pre-arranged distance.

For instance, referring particularly to Figs. 2, 3, and 4, a train or vehicle when on a section of railroad, track controlled by the track circuit battery 36 deenergizes the condoctors 7,7, of that circuit. 7, of that circuit are connected tore-lay (i and the latterwhen disengaged connects the third rail with the track section l so ll i t'it will stop any train fitted with my portable apparatus, which may contact therewith in the manner before described.
